This paper develops sophisticated data management facilities for maintaining computer-aided design (CAD) and computer-aided manufacturing (CAM) databases. The product of this research is the theoretical design of an object-oriented data model (ODM), and the implementation of an ODM computer software prototype. The work focuses on mechanical design, engineering, and manufacturing, specifically product definition data generated during initial design phases. Detailed analysis of CAD/CAM application and data management requirements were conducted to produce the ODM functional specifications. This paper presents the results of this analysis and an evaluation of ODM in achieving the goals of integrated CAD/CAM data management systems. Although most discussion concentrates on mechanical manufacturing, the developed methodology and tools for CAD/CAM data management apply to other design domains such as architecture and electronics.

This report is part of the RAND Corporation Paper series. The paper was a product of the RAND Corporation from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
